Hi all.

My Brother in law is having his new Bungalow alarmed by ADT soon. Their solution for him includes a shock sensor attached to some wide double glazing. Bro-in-law say's they say the one shock sensor will cover all the windows and the pair of central doors. The windows are about 0.5 mtr window then door then door then 0.5 mtr window. End to end the expanse is about 3.5 mtrs.( wide doors for disabled access). Would the shock of opening, prying or smashing a double glazed panel register on a single shock sensor mounted at one end?

I'm not second guessing the ADT guy, I'm interested if this is an effective way of protecting my double glazed doors.

Thanks.

Paul.

Its very hard to say, its much easier during a survey.

However i would have some concern if thats the only survey/quote he's had.

It always makes sense to get 2-3 quotes, most companies will be happy to come out free of charge.

Where abouts is he based?

Depends on the construction of the conservatory, and also perceived risk. What's in the conservatory to protect?

If they have other services like window cleaner/Gardiner these people could cause false alarms innocently.

As above, get other surveys done, even if the dotted line has been signed on, he can challenge the advice if needs be.

from what you say no. But then a picture of the door speaks thousands of words and it may.

So id advise uploading a pic of the door / windows area in question with a highlight to the location of the sensor. THen we can confirm that it wont.

It's not for me to intervene but I'll take a pic of my double glazing and would appreciate any it will/wont work.

id advise a post like that, but you need to include the proposed location else we will all be advising the best location!

I would get 3-4 surveys done then tell us the difference in detection etc.

anyone of us can recommend the best detection and types to be used, but the client often decides to reduce costs by reducing detectors.

In that case having something is better than nothing at all, It may be the sales engineer has gone for the most common place of intruder entry, which us usually the conservatory doors, and being wider than normal I suspect will have attached a vibration sensor to the header bar.

Certainly get your brother to raise his concerns promptly with the intended installer co.
